It describes how Foreign Service officers become ambassadors by rising up through the ranks, and why they typically make up about 70 percent of the total number of ambassadors. It also covers where the other 30 percent come from-the political appointees who get the job because they helped elect the president by supporting him as a campaign contributor, a political ally, or a personal friend. It explains why, despite being illegal and a threat to national security, selling the title of ambassador remains a common practice that is also unique to the United States. It considers why some suggestions for reform are misguided, what might be done, and why who the president is matters so much in determining how well the United States will be represented abroad. This updated and revised edition of Jett's classic book not only provides a timely overview of American ambassadorship for Foreign Service Officers, aspiring diplomats, and interested citizens, but also calls for much-needed reform, describing the dire implications of failing to change our ambassadorial appointments process for the future of American diplomatic practice and foreign policy.

On one side, there is the ever-increasing awareness of the adverse effects that noise and lack of acoustic comfort may have on human health. On the other, the availability of more sophisticated fabrication techniques, calculation methods, and new materials, has stimulated researchers and, more and more frequently, industry to develop customized materials with improved properties.This book collects contributions from different researchers covering several topics. A group of papers investigated the use of 3D printing to obtain perforated panels with extended frequency response, as well as to ideally design an optimized cell distribution to print (when fabrication techniques will make it possible) a porous material with a broader sound absorption. The role of the geometrical and microstructural properties of granular molecular sieves is investigated by another paper. A second group of papers focused its attention on the use of natural or recycled components to create a skeleton of porous materials with good sound-absorbing properties and low environmental impact. Cigarette butts, recycled textile waste, and almond skins have been investigated by different authors.Finally, the last batch of papers included a review of sound insulation properties of innovative concretes and two research papers focussing on a numerical and experimental analysis of wood plastic composite (WPC) panels and on the potential of semi-active solutions employing compressible constrained layer damping (CCLD).Technology: general issuesbicsscabsorber arrayacoustic propertiesagro-wasteanisotropic materialsbiopolymerscigarette buttscircular economycomposite materialscompressible constrained layer dampingconcretediffuse fieldflame retardantgraded propertieshygrothermal performancesimpedance tubelow frequency absorptionmolecular sieve pelletsmorphing structuren/anoiseoptimized absorptionorthotropic panelperforated panelperforated plates with extended tubesperiodic absorberphase change materialpolyurethane foamporous materialsradiation efficiencyrecyclingsandwich panelsemi-active dampingsound absorbersound absorptionsound transmission losssound-absorbingsound-reflectingsustainable materialsustainable materialstextile wastethermal propertytransmission lossvariability analysiswavenumber analysiswood plastic compositeTechnology: general issuesMartellotta Francescoedt1295449Martellotta FrancescoothBOOK9910557370903321Innovative Composite Materials for Sound Absorption and Insulation3023458UNINA
